Strange jelly globs

I've found a small area covered in strange, clear globs of what looks like gelatin. I've never seen this before. In the pic, the white things are perlite; you can see the shiny globby forms in between. Any ideas?

Hi Saltcedar, I think you may be looking at the white spheres. Those are perlite. The globs are completely transparent. They're like clear, runny, wiggly jello.
Ps I see you are from Austin--my favorite city!
